A year ago today, an unidentified hacker published a zipped folder in several locations online. In this folder were approximately one thousand emails and three thousand files which had been stolen from the backup server of the Climatic Research Unit in the UK, a top centre for global temperature analysis and climate change studies. As links to the folder were passed around on blogs and online communities, a small group of people sorted through the emails, picking out a handful of phrases that could be seen as controversial, and developing a narrative which they pushed to the media with all their combined strength. “A lot is happening behind the scenes,” one blog administrator wrote. “It is not being ignored. Much is being coordinated among major players and the media. Thank you very much. You will notice the beginnings of activity on other sites now. Here soon to follow.”

This was not the work of a computer-savvy teenager that liked to hack security systems for fun. Whoever the thief was, they knew what they were looking for. They knew how valuable the emails could be in the hands of the climate change denial movement.

Skepticism is a worthy quality in science, but denial is not. A skeptic will only accept a claim given sufficient evidence, but a denier will cling to their beliefs regardless of evidence. They will relentlessly attack arguments that contradict their cause, using talking points that are full of misconceptions and well-known to be false, while blindly accepting any argument that seems to support their point of view. A skeptic is willing to change their mind. A denier is not.

There are many examples of denial in our society, but perhaps the most powerful and pervasive is climate change denial. We’ve been hearing the movement’s arguments for years, ranging from illogic (“climate changed naturally in the past, so it must be natural now“) to misrepresentation (“global warming stopped in 1998“) to flat-out lies (“volcanoes emit more carbon dioxide than humans“). Of course, climate scientists thought of these objections and ruled them out long before you and I even knew what global warming was, so in recent years, the arguments of deniers were beginning to reach a dead end. The Copenhagen climate summit was approaching, and the public was beginning to understand the basic science of human-caused climate change, even realize that the vast majority of the scientific community was concerned about it. A new strategy for denial and delay was needed – ideally, for the public to lose trust in researchers. Hence, the hack at CRU, and the beginning of a disturbing new campaign to smear the reputations of climate scientists.

The contents of the emails were spun in a brilliant exercise of selective quotation. Out of context, phrases can be twisted to mean any number of things – especially if they were written as private correspondence with colleagues, rather than with public communication in mind. Think about all the emails you have sent in the past decade. Chances are, if someone tried hard enough, they could make a few sentences you had written sound like evidence of malpractice, regardless of your real actions or intentions.

Consequently, a mathematical “trick” (clever calculation) to efficiently analyse data was reframed as a conspiracy to “trick” (deceive) the public into believing the world was warming. Researchers discussed how to statistically isolate and “hide the decline” in problematic tree ring data that was no longer measuring what it used to, but this quote was immediately twisted to claim that the decline was in global temperatures: the world is cooling and scientists are hiding it from us!

Other accusations were based not on selective misquotation but on a misunderstanding of the way science works. When the researchers discussed what they felt were substandard papers that should not be published, many champions of the stolen emails shouted accusations that scientists were censoring their critics, as if all studies, no matter how weak their arguments, had a fundamental right to be published. Another email, in which a researcher privately expressed a desire to punch a notorious climate change denier, was twisted into an accusation that the scientists threatened people who disagreed with them. How was it a threat if the action was never intended to materialize, and if the supposed target was never aware of it?

These serious and potentially damaging allegations, which, upon closer examination, are nothing more than grasping at straws, were not carefully examined and evaluated by journalists – they were repeated. Early media reports bordered on the hysterical. With headlines such as “The final nail in the coffin of anthropogenic global warming” and “The worst scientific scandal of our generation“, libelous claims and wild extrapolations were published mere days after the emails were distributed. How could journalists have possibly had time to carefully examine the contents of one thousand emails? It seems much more likely that they took the short-cut of repeating the narrative of the deniers without assessing its accuracy.

Even if, for the sake of argument, all science conducted by the CRU was fraudulent, our understanding of global warming would not change. The CRU runs a global temperature dataset, but so do at least sixotheruniversitiesand government agenciesaround the world, and their independent conclusions are virtually identical. The evidence for human-caused climate change is not a house of cards that will collapse as soon as one piece is taken away. It’s more like a mountain: scrape a couple of pebbles off the top, but the mountain is still there. For respected newspapers and media outlets to ignore the many independent lines of evidence for this phenomenon in favour of a more interesting and controversial story was blatantly irresponsible, and almost no retractions or apologies have been published since.

Before long, the investigations into the contents of the stolen emails were completed, and oneby one, theycamebackclear. Six independent investigations reached basically the same conclusion: despite some reasonable concerns about data archival and sharing at CRU, the scientists had shown integrity and honesty. No science had been falsified, manipulated, exaggerated, or fudged. Despite all the media hullabaloo, “climategate” hadn’t actually changed anything.

Sadly, by the time the investigations were complete, the media hullabaloo had died down to a trickle. Climategate was old news, and although most newspapers published stories on the exonerations, they were generally brief, buried deep in the paper, and filled with quotes from PR spokespeople that insisted the investigations were “whitewashed”. In fact, Scott Mandia, a meteorology professor, found that media outlets devoted five to eleven times more stories to the accusations against the scientists than they devoted to the resulting exonerations of the scientists.

Six investigations weren’t enough, though, for some stubborn American politicians who couldn’t let go of the article of faith that Climategate was proof of a vast academic conspiracy. Senator James Inhofe planned a McCarthy-like criminal prosecution of seventeen researchers, most of whom had done nothing more than occasionally correspond with the CRU scientists. The Attorney General of Virginia, Ken Cuccinelli, repeatedly filed requests to investigate Dr. Michael Mann, a prominent paleoclimatic researcher, for fraud, simply because a twelve-year-old paper by Mann had some statistical weaknesses. Ironically, the Republican Party, which prides itself on fiscal responsibility and lower government spending, continues to advocate wasting massive sums of money conducting inquiries which have already been completed multiple times.

Where are the politicians condemning the limited resources spent on the as yet inconclusive investigations into who stole these emails, and why? Who outside the scientific community is demanding apologies from the hundreds of media outlets that spread libelous accusations without evidence? Why has the ongoing smear campaign against researchers studying what is arguably the most pressing issue of our time gone largely unnoticed, and been aided by complacent media coverage?

Fraud is a criminal charge, and should be treated as such. Climate scientists, just like anyone else, have the right to be presumed innocent until proven guilty. They shouldn’t have to endure this endless harassment of being publicly labelled as frauds without evidence. However, the injustice doesn’t end there. This hate campaign is a dangerous distraction from the consequences of global climate change, a problem that becomes more difficult to solve with every year we delay. The potential consequences are much more severe, and the time we have left to successfully address it is much shorter, than the vast majority of the public realizes. Unfortunately, powerful forces are at work to keep it that way. This little tussle about the integrity of a few researchers could have consequences millennia from now – if we let it.

Let’s start with the obvious – the U.S. midterm elections are upon us, and it’s quite likely that the Republicans will win a majority. (My American friends tell me that this is possible even with Barack Obama remaining president. Please bear with my limited knowledge of the American political system. It works very differently in Canada.)

I’m not going to comment on partisan issues – health care, immigration, economic stimulus. What I am here to talk about is an issue that should not be partisan, but has become partisan regardless: science, specifically climate science.

Climate change is not a theory – it is the logical result of several theories, based in physics and chemistry, that scientists have understood since the 1800s. What’s political about that? Exactly what part of the equation dF = 5.35 ln(C/Co) is an opinion that differs based on ideological factors?

The political part comes when we ask the question, “What do we do to stop climate change?” A carbon tax? Cap-and-trade? Regulation? Some of these solutions are more liberal or conservative than others. The only decision that doesn’t adhere to U.S. politics is to do nothing. Absence of action is a decision in itself, and the overwhelming scientific evidence (based not just on computer models, but also observations of past climate changes) shows us that doing nothing will allow this problem to spiral out of control, causing damages that no amount of money will be able to repair. What U.S. party advocates leaving that kind of world to their grandchildren? As Bill McKibben says, you wouldn’t expect it to be the Republicans:

If there was ever a radical project, monkeying with the climate would surely qualify. Had the Soviet Union built secret factories to pour carbon dioxide into the atmosphere and threatened to raise the sea level and subvert the Grain Belt, the prevailing conservative response would have been: Bomb them. Bomb them back to the Holocene—to the 10,000-year period of climatic stability now unraveling, the period that underwrote the rise of human civilization that conservatism has taken as its duty to protect. Conservatism has always stressed stability and continuity; since Burke, the watchwords have been tradition, authority, heritage. The globally averaged temperature of the planet has been 57 degrees, give or take, for most of human history; we know that works, that it allows the world we have enjoyed. Now, the finest minds, using the finest equipment, tell us that it’s headed toward 61 or 62 or 63 degrees unless we rapidly leave fossil fuel behind, and that, in the words of NASA scientists, this new world won’t be “similar to that on which civilization developed and to which life on earth is adapted.” Conservatives should be leading the desperate fight to preserve the earth we were born on.

It is questionable whether all of these statements are sincere. Politicians, after all, will say whatever they need to say to get elected. If these Republicans feel that their voting base denies climate change, they will adjust their public statements accordingly. Look at John McCain – during the 2008 presidential election, his promises for clean energy were nearly as strong as Obama’s. Now, he rejects cap-and-trade, and views the anthropogenic cause of climate change in the Arctic as an “opinion”.

Admittedly, a new, but growing, segment of the Republican voting base overwhelmingly denies climate change. As the New York Times reports, Tea Party supporters have all kinds of convoluted arguments against a field of science they know virtually nothing about. It contradicts “the preaching of Rush Limbaugh and the teaching of Scripture”, and it could be caused by “the normal cycles of nature” (whatever those are), so thousands of scientists spending their lives studying this problem must be missing something. Or they could be part of a massive conspiracy.

Republican candidates are catering to the extreme segments of their party, and, arguably, to their party as a whole. However, their plans to base action (or lack thereof) on the fervent hope that the scientific community is out to lunch may alienate voters who understand what a risk that would be.

Or so we hope. If Republicans get their way, climate science will not just be disregarded: the men and women who study it will be criminally investigated, for no reason other than that their research supports the existence of anthropogenic climate change. And since James Inhofe can’t find any gaping holes in the math, that means the scientists must be fraudulent, right?

The Republican Party also hopes to conduct yet another investigation into the private correspondence of scientists, stolen and distributed a year ago. Although these emails show that climate scientists are not always very nice, it does not undermine one iota of our understanding of the climate system, as five independent investigations have concluded. But that’s not the answer Republican officials want, so they will waste taxpayers’ money and researchers’ time with their own investigation. Kind of hypocritical for a party that promises fiscal responsibility.

I’m a Canadian. I don’t get a vote in this election. I am also eighteen years old. I, unlike most Republican Senators, will be around to witness the effects of climate change. We have wasted twenty years in the fight against climate change, and if we continue to let petty politics and finger-pointing delay us more, the whole world will suffer.

It’s no secret that American politics disproportionately influence the world. The same is true for American emissions of greenhouse gases, and American agreements to reduce these emissions, and American patterns of energy use and energy sources. So please, when you go to vote this week, think about not just yourself and your country but other young people and other countries too.

If you don’t vote because you’re trying to teach politicians a lesson, you’re tragically misguided in your strategy. The very politicians you’re trying to send a message to don’t want you to vote.

Voting is free. It’s fairly fast. It doesn’t make you responsible for the outcome, but it sure has an impact on what we have to live with going forward. The only thing that would make it better is free snacks.

I think that action to mitigate climate change has been so slow (in many cases, nonexistent) partly because the problem is just so massive. At every single level – individual, politician, government, country – people think that they can’t possibly solve it on their own, so there’s no point in trying at all.

It’s not the same kind of problem as something like world poverty, or disease in developing countries. In a way, I wish it was. It’s not really possible for a single person to solve these problems either, but at least they can solve it for someone. They can pay for a child’s education in Africa. They can build a well with clean water for an entire community. These types of problems are measured in increments, rather than gradients – just like the corpuscular theory of light. The problem comes in small packages of one person each, and even if you can’t eliminate the problem for everyone, you can chip away.

Conversely, climate change is a gradient, and one that is very resistant to reversal. Even if a family manages to completely eliminate all sources of carbon emissions in their life, they’re only preventing a fraction of a fraction of a fraction of a degree of warming. 2.999997 C warming isn’t very different to 3 C. And that difference of 0.000003 C isn’t changing the life of a child. (These are just arbitrary numbers, don’t quote me on them!) Really, it isn’t having any impact at all. So most people don’t even bother. They feel so powerless – after all, this problem is far too big for them to solve.

I believe that individual action on climate change is definitely worth it, but in a more symbolic manner. No, composting your kitchen waste isn’t going to eliminate enough methane to make a difference in the global radiative forcing of greenhouse gases. But it gets you in the right mindset. It makes you stop and think about the planet and the future. And the chance that you might inspire all yourfriends and neighbours to compost as well, who would then inspire all of their friends, and eventually start a chain reaction that could, conceivably, start to make a difference, is just too good to pass up. (Besides, composting is fun to watch. We get some very cool slugs hanging out around ours this time of year.)

Regardless, the feeling of powerlessness becomes the norm, to the point where even politicians don’t think they can make any difference. I have a friend who asked his MP, a Liberal, what she was going to do about climate change. Her response was, “What can I do? I’m only one person.” I find it absolutely astounding that a politician who represents tens of thousands of people, and who helps to govern the entire country, could have this attitude. It’s kind of sad when even our Members of Parliament feel powerless.

Of course, Canada’s national position on climate change action is “whatever the States decides, and we won’t do anything at all unless and until they do”. The federal government feels powerless too, because (as they constantly remind us) Canada produces only 2% of the world’s greenhouse gas emissions. What’s the point of reducing them if the U.S. isn’t going to do the same?

We all know that the U.S. isn’t going to pass cap-and-trade any time soon. It looks like the Republicans are keeping their promise of preventing Obama from passing any more sweeping legislation, after the health care bill. And a big reason (or at least a common excuse) for this lack of initiative is that India and China will soon produce most of the world’s carbon emissions. What’s the point of the U.S. making any mitigating effort if the soon-to-be-major-players won’t?

What federal governments fail to realize is that they have far more power than they give themselves credit for. If the U.S. decides that they want a global economy of clean energy, they have enough influence over the market to make that happen. If Canada decides that tar sands actually aren’t such a good idea after all, all the countries that import from us will have to find alternatives. But this hasn’t happened, because governments are far more concerned about the next election.

At times like these, I just want to look politicians in the eyes and tell them to wake up. Stop playing games, pointing fingers, and sabotaging your enemies. Remember that your job is to look out for us, and start getting serious on a crisis that is unprecedented in all of human history – one that we could all avoid, even now, if you just got your acts together.

I am now a voting member of the public, a legal adult. And I don’t have a clue who to vote for, because nearly every politician has lost my support. If they cared at all about the kind of world I will live in after they are gone, and the kind of world the children I hope to have will live in after I am gone, they would start doing their jobs. I think I will find myself voting against politicians, rather than for politicians. I will vote for those who are the least bad, so that the worst don’t get into office.

I am not optimistic about climate change, but I know that we have a chance to prevent the worst of it. I am not optimistic, but I do not feel powerless. I believe in the power of knowledge and inspiration and culture. I believe in the potential of accomplishing a great deal in a short period of time. At some point in this chain of people who are overwhelmed or apathetic, something needs to give.

Remember back in December, when the news was buzzing each day about the stolen emails from top climate researchers? They were described as “the final nail in the coffin of anthropogenic global warming”, or worse. Apparently, the scientists had written things that severely compromised the underpinnings for the idea that human activity was causing the Earth to warm. We could now all stop worrying and forget about cap-and-trade.

But that wasn’t the end of the story. There were no less than four independent investigations into the contents of these emails – conducted by scientists, universities, and governments, not general reporters rushing off a story about an area of science with which they were unfamiliar, and trying to make it sound interesting and controversial in the process.

So what did these investigations find? Is the Earth still warming? Are humans still responsible? Can we trust the scientific process any more, or should we throw peer-review out the window and practice Blog Science instead?

Actually, all four of the investigations concluded that absolutely no science was compromised by the contents of the emails. The CRU scientists weren’t as good as they should have been about making data easily accessible to others, but that was the only real criticism. These scientists are not frauds, although they are accused of it on a daily basis.

Pennsylvania State University, over a series of tworeports, investigated the actions of their employee, Dr. Michael Mann, who is arguably at the top of the field of paleoclimatology. They found that, contrary to most accounts in the mainstream media, he did not hide or manipulate any data to exaggerate global warming, delete any emails that might seem suspicious and be subject to Freedom of Information requests, or unjustly suppress skeptical papers from publication. After a second investigation, following up on the catch-all accusation of “seriously deviating from accepted practices within the academic community”, Penn State exonerated Mann. They criticized him for occasionally sharing unpublished manuscripts with his colleagues without first obtaining the express permission of the authors, but besides that minor (and somewhat unrelated) reprimand, they found absolutely nothing wrong.

The British House of Commons investigated the actions of CRU director Phil Jones, and came to a similar conclusion. They found that his “actions were in line with common practice in the climate science community”, that he was “not part of a systematic attempt to mislead” or “subvert the peer review process”, and that “the focus on CRU….has been largely misplaced”. They criticized CRU’s lack of openness with their data, but said that the responsibility should lie with the University of East Anglia, which CRU is a part of. So these scientists should really catch up to the climate research team at NASA, for example, which publishes all of their raw data, methodologies, and computer codes online, with impeccable archives.

The University of East Anglia conducted their own investigation into the actions of CRU as a whole. They found “no hint of tailoring results to a particular agenda”, and asserted that “allegations of deliberate misrepresentation and unjustified selection of data are not valid”. They also explored the lack of transparency in CRU, but were more sympathetic. “CRU accepts with hindsight”, they write, “that they should have devoted more attention in the past to archiving data and algorithms and recording exactly what they did. At the time the work was done, they had no idea that these data would assume the importance they have today and that the Unit would have to answer detailed inquiries on earlier work.” They also note that CRU should not have had to respond to Freedom of Information requests for data which they did not own (such as weather station records).

Just last week, the final investigation, headed by Sir Muir Russell on behalf of UEA, found that “their rigour and honesty as scientists are not in doubt.” Is this starting to seem a bit repetitive? To illustrate their point, over the course of two days, they independently reconstructed the global temperature record using publicly available data, and came to the same conclusion as CRU. Again, there was the criticism that CRU was not as open as it should have been. They also noted that an obscure cover figure for a 1999 World Meteorological Organization report, constructed by Phil Jones, did not include enough caveats about what was proxy data and what was instrumental data. However, the more formally published, and much more iconic, graphs in Mann 98 and the IPCC TAR, were fine.

There have been some great comments on the results of these investigations since they were released, especially by scientists. Here are some samples:

[The CRU researchers] are honest, hardworking scientists whose reputations have been unjustifiably smeared by allegations of unscrupulous behaviour…I hope that the media will devote as much attention to this comprehensive dismissal of the allegations as it did to promoting the hysteria surrounding the email theft in the first place. Will the Daily Telegraph now retract its claim that the emails revealed “the greatest scientific scandal of our age” and apologize unreservedly to Phil Jones? Will there now be a public inquiry about the erroneous, shallow and repetitive nonsense promulgated in the media over this affair? If there is a scandal to be reported at all, it is this: the media stoked a controversy without properly investigating the issues, choosing to inflate trivialities to the level of an international scandal, without regard for the facts or individuals affected. This was a shameful chapter in the history of news reporting. -Raymond Bradley, director of the Climate System Research Center at the University of Massachusetts

The call for greater transparency and openness among scientists and their institutions is necessary and welcomed, but certainly they aren’t the only ones who deserve that reminder. What institution on the planet would pass muster under such intense scrutiny? Certainly not the U.S. government agencies, which often deny or impede FOIA requests, or global corporations like BP, Massey Energy and Koch Industries, which seem to revel in hiding information from the public all the time. More transparency is needed everywhere, not just among scientists in lab coats. -Brendan DeMelle, freelance journalist, DeSmogBlog

[The Muir-Russell report] makes a number of recommendations for improvements in processes and practices at the CRU, and so can be taken as mildly critical, especially of CRU governance. But in so doing, it never really acknowledges the problems a small research unit (varying between 3.5 to 5 FTE staff over the last decade) would have in finding the resources and funding to be an early adopter in open data and public communication, while somehow managing to do cutting edge research in its area of expertise too. -Steve Easterbrook, computer science professor at the University of Toronto

I agree with these statements. I think that we are holding scientists in general, but especially climate scientists, to a far higher standard than any other group of people in the world. We need to relax a bit and realize that scientists make mistakes, and that innocent mistakes are not evidence of fraud that will bring a long-standing theory tumbling down. We need to realize that scientists are employees like any others, who don’t always follow ideal actions in every professional situation, especially when they are under intense pressure that includes death threats and accusations of criminal activity.

However, at the same time, we need to start holding other groups of people, especially journalists, to a higher standard. Why has the media been able to get away with perpetuating serious allegations without first investigating the what really happened, and without publishing explicit retractions and apologies when the people whose reputations they smeared are found innocent? Why haven’t there been four official investigations into who stole these emails, and why?

I really enjoyed reading two recent polls conducted by George Mason University’s Center for Climate Communication. In particular, the results made me wonder why the US government still hasn’t passed a climate bill.

For example, US presidents have been saying for over a decade that it is unfair to force their industries to reduce emissions if developing countries do not have similar targets. However, only 8% of American adults share this view, and 65% believe that “the United States should reduce its greenhouse gas emissions regardless of what other countries do.” 77% agree that CO2 should be regulated, and 65% would like to see an international treaty signed.

The only solution which had less than 50% support was a tax on gasoline, even if it was revenue-neutral: offset by a decrease in income tax rates. This opposition can’t really be a case of people worrying about money. In this hypothetical situation, taxes aren’t being increased – they’re just being moved around, in a way that actually gives people more control over how much they are charged. Perhaps the public would prefer a more laissez-faire approach, or perhaps they had a knee-jerk reaction to the word “tax”. It’s not like the revenue-neutral aspect of this solution is well-known to most.

When the poll was broken down by political party, there were some surprising results that ran contrary to what one hears in the halls of Congress. 64% of Republicans support regulating CO2. Only 30% think that protecting the environment reduces economic growth and costs jobs.

Overall, the poll showed very strong support among Americans for action that still hasn’t happened, largely because a very vocal minority has had a disproportionate influence on the policy debate. If there was a referendum today, Kyoto targets and the cap-and-trade bill would pass with flying colours.

This support was even more interesting when compared to the questions regarding science. Only 61% of Americans think that the Earth is warming, and only 50% think that it is due to human activities. 45% think “there is a lot of disagreement among scientists about whether or not global warming is happening”, and only 34% were aware of the existing consensus.

The discrepancy between scientific understanding of the issue and support for mitigation shows that Americans, in general, practice risk management when it comes to climate change. Even if they’re not sure whether or not there is a problem, they understand what is at risk, and are willing to take action to prevent major consequences. Greg Craven, you got your wish.

I think that the misconception of a voracious scientific debate, apart from being perpetrated by the media, stems partly from the fact that most of the public lacks the experience to distinguish between scientific and quasi-scientific debates. Competing hypotheses, published in leading journals, seen as the frontier of the field….that’s a scientific debate. Editorials, written by anyone other than a scientist publishing in the field, claiming to refute an overwhelming consensus? Can’t even come close. However, I suspect that many would categorize the second as “scientific debate”, simply because it’s their only encounter with science.

All is not lost, though. 81% of Americans trust scientists as a source of information about global warming. That’s more than they trust any other source that was mentioned in the question. And 20%, 27%, and 29% say that they need a lot more, some more, or a little more information, respectively. Maybe all that needs to happen is for us to speak louder – because people are ready and willing to listen.

I really enjoyed this post by Andrew Freedman on the Washington Post blog Capital Weather Gang. I think it is written at the perfect level – basic enough for new readers to catch up on current events, while including enough creative insights to keep the interest of climate science enthusiasts.

The article covers the attempts of Dr Andrew Weaver, a top Canadian climate modeler, to fight back at the misinformation that has been willingly spread by top media outlets throughout the past few months. Here is an excerpt:

In late April Weaver filed suit against the National Post, a Canadian newspaper that has run numerous articles extremely critical of Weaver’s work and those of his colleagues. For example, according to Wihbey, the Post has called Weaver “Canada’s warmist spinner in chief,” and “generally impute[ed] to Weaver various views that he claims he doesn’t have.” (Weaver’s requests that the newspaper correct the record by issuing retractions/corrections were unsuccessful).

In the lawsuit, Weaver, who was a lead author of one of the IPCC’s working groups for its 2007 report, claims the articles include “grossly irresponsible falsehoods that have gone viral on the Internet.” Among those claims is that Weaver has turned against the IPCC and its conclusions, as trumpeted in this story in late January.

“If I sit back and do nothing to clear my name, these libels will stay on the Internet forever,” Weaver stated. “They’ll poison the factual record, misleading people who are looking for reliable scientific information about global warming.”

I am impressed at Dr Weaver’s courage and persistence to improve the accuracy of science journalism. For an issue that has potential consequences of an unprecedented scale in human history, we should be able to trust what the media tells us.

Something else I enjoyed was a sketch by Mitchell and Webb, a British comedy duo, making fun of how politicians pretend to promise action on climate change. Enjoy.

Yet when it comes to coverage of global warming, we are trapped in the logic of a guerrilla insurgency. The climate scientists have to be right 100 percent of the time, or their 0.01 percent error becomes Glaciergate, and they are frauds. By contrast, the deniers only have to be right 0.01 percent of the time for their narrative–See! The global warming story is falling apart!–to be reinforced by the media.
